LIGO detects gravitational waves for third time
LIGO detects gravitational waves third time
2017/7/21
The collision of a pair of colossal, stellar-mass black holes has made itself heard, nearly 3 billion light years away, through a cosmic microphone on Earth.
On Jan. 4, the Laser Interferometry Gravi...
People used to establish physical laws on the mathematical frame directly, without considering the existence of the No-Shape-Substance. We believe such physical laws are separated from their nature. S...
Comparing space+time decompositions in the post-Newtonian limit
space+time decompositions post-Newtonian limit
2010/12/20
We compare the Arnowitt-Deser-Misner (ADM) field decomposition with the Non-Relativistic Gravitational (NRG) fields for the purpose of computing the two-body post-Newtonian (PN) effective action withi...
Lurching Toward Chernobyl: Dysfunctions of Real-Time Computation

2011/9/8
Cognitive biological structures, social organizations, and computing machines operating in real time are subject to Rate Distortion Theorem constraints driven by the homology between information sourc...
Propagation of extended objects across singularity of time dependent orbifold
cosmological singularity p-brane Milne space
2010/3/18
In this paper we argue that the compactified Milne space is a promising model of the cosmological singularity. It is shown that extended objects like strings propagate in a well-defined manner across ...
Late time behavior of closed isotropic models in second order gravity theory
closed isotropic models order gravity theory
2010/3/17
Homogeneous and isotropic closed models are studied in both the Einstein and the Jordan frame of the second order gravity theory. The normal form of the dynamical system has periodic solutions for a l...
